简要总结
Prosthetic rehabilitation of acquired maxillary defects represents a challenging mission for both the prosthodontist and psychologically traumatized patients. These defects may be due to trauma, pathological conditions, or surgical resection of oral tumors. The resulting main problem is oronasal communication leading to impairment in mastication, swallowing, speech, and facial esthetics
详细描述
Maxillary obturator prostheses are usually fabricated from polymethyl methacrylate (PMMA) if the patient is completely edentulous, or from PMMA and a cast frame-work if partially edentulous. As the size of the surgical resection increases, the weight of the prosthesis also increases. Traditionally, the weight of the prosthesis has been minimized through the use of hollow bulb obturators and change of manufacturing material.
Polyetherketoneketone (PEKK) has been widely tested in a number of dental applications, such as PEKK dental implants, PEKK obturators, and PEEK RPD frameworks. PEKK has a relatively low Young's modulus of 3 to 4 GPa, which is close to that of human bones, and its tensile properties are similar to those of bone, enamel, and dentin. These properties make it a suitable material for fixed and removable prostheses.(6-8) PEKK is a lightweight material with excellent biocompatibility as it can be used in combination with Computer-aided design/computer-assisted manufacturing (CAD/CAM) in fabrication of maxillofacial prostheses.(9) So the aim of this study will be, evaluation of Patient satisfaction and oral healthy related quality of life of PEKK and metal framework for management of maxillectomy cases. The null hypothesis is that, there would be no significant difference between both frameworks.
